• the positions of the at least two sidewalls and at least two endwalls may also be altered to form castings of different widths, depths, and shapes, as described more fully below.
• a purpose of the adapter 16 is to be easily removed from the core 20 and/or connector 21 and molding material so that the outer portion 14 and the core 20 can be reused with adapters 16 and connectors 21 of various configurations, e.g., shapes, slopes, sizes, etc., to thereby form molds 8 and castings of various configurations, e.g., shapes, slopes, sizes, etc.
• the external surface and shape 30 of the adapter 16 is a half circle-like configuration comprised of three planar sides. This design reduces the stress concentration in a drainage channel casting. Specifically, in such embodiment, stress is reduced in the corners of the internal surface of the casting, such as a drainage channel, as compared to the stress concentration in the corners of a traditional, rectangular casting.

Moving the position of the core 20 within the outer portion 14 toward the floor 6 increases the overall height of the mold 8, while moving the position of the core 20 within the outer portion 14 away from the floor 6 decreases the overall height of the mold 8.
• the overall height of the mold 8 is adjusted by merely removing the then-existing core 20 from the adjustable mold 10 and replacing it with a core 20 of a desired height. In yet still other embodiments, the overall height of the mold 8 is adjusted by merely removing the then-existing adapter 16 and/or connector 21 from the adjustable mold 10 and replacing it with an adapter 16 and/or connector 21 of a desired height.
• the shape of the inner portion of the mold 8, i.e., the internal surface of the casting can be adjusted by replacing the then-existing adapter 16 and/or connector 21 with an adapter and/or connector of a desired shape, thereby customizing, for example, the channel shape of a drainage channel mold and casting.

• the core walls 40 may not be permanently fixed to the core 20, allowing the core walls 40 to move away from the core 20 towards the sidewalls 28, thereby increasing the width of the core 20 and the overall width of the adjustable die 12.
• the core walls 40 are operatively coupled to one or more core wall member 42, 44, which are, in turn, operatively coupled to the base 32.
• two core wall members 42, 44 and/or two core walls 40 are configured to be removably attached to the base support 34 and/or base 32 by a mechanism, such as one or more track systems, that allows the two core wall members 42, 44, and therefore the two core walls 40, to slide toward and/or away from each other.
• Such a mechanism may include one or more locking mechanisms, such as a bolt and wing nut placed in a track, which allows a user to lock the two core wall members 42, 44 at a position and desired distance away from each other. Moving the core walls 40 farther away or closer to the core 20 at least partially adjusts the overall width of the adjustable die 12 and, thereby, may produce a casting and/or mold 8 of variable internal channel width.

• the sidewalls 28 and/or at least two endwalls can be hingedly connected to the at least one base support 34 through hinges. This hinged configuration may be useful to adjust the slope of the at least two sidewalls and/or at least two endwalls and/or for aiding in the removal of the mold 8 from the adjustable mold 10.
• the sidewalls 28 and/or endwalls may be operatively coupled directly to the base 32 instead of the at least one base member 36, 38.
• the core walls 40 and the core wall members 42, 44 may be configured in a manner similar to that of the sidewalls 28 and base members 36, 38 as previously described, allowing for the core walls 40 to be positioned at different distances and slopes relative to each other, which gives the adjustable mold 10 the flexibility to change the overall configuration, e.g., width, depth, and shape of at least a portion of the adjustable die 12, the mold 8, and, thus, the configuration of the casting, including the configuration of the internal surface of a drainage channel casting.
• Adjusting the slope of the at least two sidewalls 28, at least two endwalls, and/or at least two core walls 40 adjusts the thickness of the mold 8, and thus the thickness of the casting.
• Increasing the thickness of the casting at areas of higher stress concentration minimizes the need to use additional materials to support the casting at such areas of higher stress concentration and, thereby, reduces the cost of the casting.
